I'm not sure if it wound up and moved or if it moved from shaking it, but it probably works with manual winding. It runs, but I don't think it's working properly. You can set the time with the crown, but it slips and does other strange things, and the condition isn't good, so it's being sold as junk. I would appreciate it if anyone who is interested would carefully review the product page and images before purchasing. It will be placed in a bag, wrapped in bubble wrap, and shipped in an envelope via Yu-Yu Mercari mail from the post. I apologize for the inconvenience, but please read the profile before considering a purchase. I am not negotiating prices. I look forward to your purchase. Thank you for reading to the end. #Junk #KANGARO #CRYSTAL #17JEWELS #Men's #Wristwatch #17 Jewels
